these parameters.
Code Description
Range
5301
EFB PROTOCOL ID
0…0xFFFF
Contains the identification and program revision of the protocol.
• Format: XXYY, where xx = protocol ID, and YY = program revision.
5302
EFB STATION ID
0…65535
Defines the node address of the RS485 link.
• The node address on each unit must be unique.
5303
EFB BAUD RATE
1.2, 2.4, 4.8, 9.6, 19.2,
Defines the communication speed of
38.4, 57.6, 76.8 kb/s
the RS485 link in kbits per second (kb/s).
1.2 kb/s
2.4 kb/s
4.8 kb/s
9.6 kb/s
19.2 kb/s
38.4 kb/s
57.6 kb/s
76.8 kb/s
5304
EFB PARITY
0…3
Defines the data length parity and stop bits to be used with the RS485
link communication.
• The same settings must be used in all on-line stations.
0 = 8
NONE
1 – 8 data bits, no parity, one stop bit.
1 = 8
NONE
2 – 8 data bits, no parity, two stop bits.
2 = 8
EVEN
1 – 8 data bits, even parity, one stop bit.
3 = 8
ODD
1 – 8 data bits, odd parity, one stop bit.
5305
EFB CTRL PROFILE
0…2
Selects the communication profile used by the EFB protocol.
0 =
ABB
DRV
LIM
– Operation of the Control Word and Status Word
conforms to ABB Drives Profile, as used in ACS400.
1 =
DCU
PROFILE
– Operation of Control/Status Words conforms to 32-bit
DCU Profile.
2 =
ABB
DRV
FULL
– Operation of Control/Status Words conforms to ABB
Drives Profile, as used in ACS600/800.
5306
EFB OK MESSAGES
0…65535
Contains a count of valid messages received by the drive.
• During normal operation, this counter is increasing constantly.
